Virus.DOS.StealthBomber is a DOS-based computer virus known for its stealth capabilities. This virus infects executable files (.COM and .EXE) and employs various techniques to avoid detection by antivirus programs. Once activated, StealthBomber can hide its presence by intercepting system calls and preventing infected files from being modified or detected. The virus spreads by attaching itself to other executable files and activates when these files are run. While not as damaging as some other viruses, Virus.DOS.StealthBomber's ability to evade detection and spread unnoticed makes it a notable example of early stealth malware.
